+# Budget Site — Implementation Plan
+
+## Overview
+
+Replace a Google Docs spreadsheet with a multi-user budget web app. Users get Income, Outgo, and Summary views organized around the 50/30/20 framework. Budgets can be shared with other users in edit or view-only mode.
+
+**Stack:**
+- Backend: ASP.NET Core (serves API + hosts compiled React assets)
+- Frontend: Vite + React (TypeScript)
+- Database: PostgreSQL via EF Core
+- Auth: OIDC against `auth.stwaddle.com` (OpenIddict-based)
+- Deployment: Single Docker container (no nginx needed)
+
+---
+
+## Frequency Reference
+
+All monetary amounts are normalized to monthly and annual values using these multipliers:
+
+| Frequency     | Monthly Multiplier        | Notes                           |
+|---------------|---------------------------|---------------------------------|
+| Biennial      | amount / 24               | Once every 2 years              |
+| Annually      | amount / 12               | Once per year                   |
+| Biannually    | amount × 2 / 12           | Twice per year                  |
+| Quarterly     | amount × 4 / 12           | 4× per year                     |
+| Every 2 Months| amount × 6 / 12           | Every other month (6× per year) |
+| Monthly       | amount × 1                |                                 |
+| Semi-monthly  | amount × 2                | Twice per month                 |
+| Biweekly      | amount × 26 / 12          | Every 2 weeks                   |
+| Weekly        | amount × 52 / 12          | Every week                      |

+
+## Architecture
+
+### Single-Container Strategy
+
+The ASP.NET Core app serves the Vite production build from its `wwwroot` directory. The Dockerfile is a two-stage build:
+
+1. **Stage 1 (node):** `npm run build` inside `client/` → outputs to `client/dist/`
+2. **Stage 2 (dotnet):** Publishes the ASP.NET app, copies `client/dist` into `wwwroot/`
+
+At runtime, ASP.NET uses `UseStaticFiles()` + a catch-all fallback route that returns `index.html` for any non-API path (SPA fallback). API routes are prefixed `/api`.
+
+### Development Mode
+
+In development the Vite dev server runs separately (e.g., `localhost:5173`). ASP.NET proxies unknown routes to it via `Microsoft.AspNetCore.SpaProxy` or a simple reverse proxy middleware. A `launchSettings.json` profile wires this up so `dotnet run` and `npm run dev` together give hot-reload on both sides.

+## Data Model
+
+### Entities
+
+**Budget**
+- `Id` (Guid)
+- `Name` (string)
+- `OwnerUserId` (string — `sub` claim from OIDC token)
+- `CreatedAt`, `UpdatedAt`
+
+**Income**
+- `Id` (Guid)
+- `BudgetId` (Guid, FK)
+- `Name` (string)
+- `Frequency` (enum)
+- `Amount` (decimal)
+- `SortOrder` (int) — preserves user-defined row ordering
+
+**Outgo**
+- `Id` (Guid)
+- `BudgetId` (Guid, FK)
+- `Name` (string)
+- `Category` (string, nullable)
+- `Type` (enum: Need | Want | Save)
+- `Frequency` (enum)
+- `Amount` (decimal)
+- `PaymentSource` (string, nullable)
+- `Notes` (string, nullable)
+- `SortOrder` (int)
+
+> `Monthly`, `Annually`, and `MonthlyPercentage` are computed — not stored. The API returns them as calculated fields in DTOs.
+
+**KnownUser** *(local cache of authenticated users)*
+- `Id` (string — the OIDC `sub` claim, PK)
+- `Email` (string)
+- `Name` (string)
+- `LastSeenAt` (DateTimeOffset)
+
+> Populated/updated each time a user authenticates with the Budget app. Used for the share-by-email lookup flow without requiring any changes to the Auth server.
+
+**BudgetShare**
+- `Id` (Guid)
+- `BudgetId` (Guid, FK)
+- `SharedWithUserId` (string, nullable) — null until the target user has logged in
+- `SharedWithEmail` (string) — the email used when the share was created; used to resolve pending shares on login
+- `Permission` (enum: View | Edit)
+- `IsPending` (bool) — true when `SharedWithUserId` is null
+- `CreatedAt`
+
+> When a user authenticates, the app queries for pending shares where `SharedWithEmail` matches their token's `email` claim, sets `SharedWithUserId` and clears `IsPending`. This allows pre-sharing with users who haven't logged in yet without any Auth server changes or enumeration risk.
+
+### Authorization Rules
+
+- Only the budget owner or a user with Edit permission may mutate data.
+- A user with View permission may read all budget data.
+- A user with no share record (resolved or pending) may not access the budget.
+- The owner may not be removed from their own budget.
+- Pending shares are not counted for access until resolved.

+  }
+}
+```
+
+---
+
+## Pre-Tax Income Calculator
+
+The calculator takes a configurable effective tax rate (stored per-budget, defaulting to 25%) and computes:
+
+```
+minimumAnnualGross = annualOutgoTotal / (1 - effectiveTaxRate)
+```
+
+The effective tax rate is stored on the Budget entity and editable from the Summary page via a settings panel.
+
+---
+
+## Frontend Pages & Components
+
+### Routing
+
+```
+/                        → redirect to /budgets
+/budgets                 → budget list / selector
+/budgets/:id/income      → Income page
+/budgets/:id/outgo       → Outgo page
+/budgets/:id/summary     → Summary page
+/budgets/:id/settings    → Budget settings (sharing, tax rate)
+```
+
+### Income Page
+
+Editable table with columns: Name, Frequency, Amount, Monthly, Annually.
+
+- Inline editing (click a cell to edit)
+- Add row button at bottom
+- Delete row button per row
+- Drag-to-reorder rows
+- Monthly and Annually columns are read-only computed displays
+
+### Outgo Page
+
+Editable table with columns: Name, Category, Type, Frequency, Amount, Monthly, Annually, Payment Source, Monthly%, Notes.
+
+- Same inline editing / add / delete / reorder as Income
+- **Category**: free-text input with dropdown suggestions sourced from `/outgos/categories`
+- **Payment Source**: same autocomplete pattern via `/outgos/payment-sources`
+- **Type**: dropdown (Need / Want / Save)
+- **Monthly%**: read-only computed
+- Monthly and Annually: read-only computed
+
+### Summary Page
+
+- Header card: Monthly Income, Annual Income
+- Table of types (Need, Want, Save, Unspent) with columns: Type, Monthly Total, Annual Total, % of Income, Target %, Max Amount, Remaining
+  - Target % shown as a tooltip/info icon rather than a data column to reduce visual noise
+  - Unspent row only shows Total, Annually, %
+- Pre-Tax Income section: shows minimum annual gross with an editable tax rate field
+
+### Budget Settings Page
+
+- Rename budget
+- Effective tax rate input
+- Shares table: list current shares, add by user email/ID, change permission, revoke
+
+### Shared Components
+
+- `FrequencySelect` — dropdown for the 9 frequency options
+- `MoneyDisplay` — formatted currency display
+- `AutocompleteInput` — reusable input with suggestions dropdown
+- `BudgetNav` — tabs: Income | Outgo | Summary | Settings
+- Auth guard wrapping all budget routes
+
+---
+
+## Authentication
+
+Auth is handled by the external OIDC provider at `auth.stwaddle.com`.
+
+### Backend
+
+- Add `Microsoft.AspNetCore.Authentication.JwtBearer`
+- Configure authority and audience from environment variables:
+  ```
+  AUTH__AUTHORITY=https://auth.stwaddle.com
+  AUTH__AUDIENCE=budget-api
+  ```
+- All `/api` endpoints require `[Authorize]`
+- Extract `sub` claim as the user identity key
+
+### Frontend
+
+- Use `oidc-client-ts` (or `@axa-fr/react-oidc`) for the OIDC flow
+- Store the access token and attach it as `Authorization: Bearer <token>` on all API calls
+- Auth config sourced from env vars baked in at build time:
+  ```
+  VITE_AUTH_AUTHORITY=https://auth.stwaddle.com
+  VITE_AUTH_CLIENT_ID=budget-client
+  VITE_AUTH_REDIRECT_URI=https://budget.stwaddle.com/callback
+  ```
+
+Auth integration is scaffolded in Phase 2 but login/callback pages are left as stubs; full OIDC flow requires a client registration on `auth.stwaddle.com` (done via the Auth admin UI — create a Public client with Authorization Code + PKCE, add the budget app's redirect URI, and assign the `email`, `profile`, and `roles` scopes).
+
+### User Identity Cache & Pending Share Resolution
+
+On every authenticated request, the Budget API upserts a `KnownUser` record using the `sub`, `email`, and `name` claims from the token. After upserting, it resolves any pending shares by matching `SharedWithEmail` to the user's email claim, setting `SharedWithUserId` and clearing `IsPending`.
+
+---
+
+## Configuration & Environment
+
+`.env.example`:

+POSTGRES_USER=budget
+POSTGRES_PASSWORD=changeme

+
+## Implementation Phases
+
+### Phase 1 — Project Scaffolding & Infrastructure
+- [ ] Create `src/Budget.Api` ASP.NET Core Web API project (targeting .NET 9)
+- [ ] Create `src/Budget.Client` Vite + React + TypeScript project
+- [ ] Add both to `Budget.sln`
+- [ ] Configure ASP.NET to serve static files from `wwwroot` with SPA fallback
+- [ ] Configure Vite dev proxy to forward `/api` requests to the ASP.NET dev port
+- [ ] Add EF Core + Npgsql packages; scaffold `AppDbContext`
+- [ ] Define all entity models and configure EF mappings
+- [ ] Add initial migration
+- [ ] Write `Dockerfile` (multi-stage as above)
+- [ ] Write `.env.example`
+- [ ] Verify clean build: `dotnet build` + `npm run build`
+
+### Phase 2 — Authentication Scaffolding
+- [ ] Add JWT bearer auth to ASP.NET; read authority/audience from config
+- [ ] Add `[Authorize]` to a test endpoint and verify token validation works
+- [ ] Add middleware to upsert `KnownUser` and resolve pending shares on each authenticated request
+- [ ] Add `oidc-client-ts` to the React app
+- [ ] Create auth context / provider with login, logout, and token storage
+- [ ] Add stub `/callback` route for OIDC redirect
+- [ ] Protect all budget routes with an auth guard
+- [ ] Verify clean build
+
+### Phase 3 — Budget & Sharing API
+- [ ] `BudgetsController`: CRUD + list
+- [ ] Authorization service: checks owner vs. share permissions
+- [ ] `SharesController`: list / add / update / delete
+- [ ] Apply authorization service to all budget-scoped controllers
+- [ ] Integration-test the happy paths manually
+- [ ] Verify clean build
+
+### Phase 4 — Income API & Page
+- [ ] `IncomesController`: list, add, update, delete, reorder
+- [ ] Frequency calculation service (shared utility used by all computed fields)
+- [ ] Income list DTO including computed Monthly and Annually
+- [ ] React Income page: table, inline edit, add/delete row, drag reorder
+- [ ] `FrequencySelect` and `MoneyDisplay` shared components
+- [ ] Verify clean build
+
+### Phase 5 — Outgo API & Page
+- [ ] `OutgosController`: list, add, update, delete, reorder, categories, payment-sources
+- [ ] Outgo list DTO including Monthly, Annually, MonthlyPercentage
+- [ ] React Outgo page: table with all columns, inline edit, add/delete, reorder
+- [ ] `AutocompleteInput` component wired to categories and payment-sources endpoints
+- [ ] Verify clean build
+
+### Phase 6 — Summary API & Page
+- [ ] `SummaryController`: compute and return full summary shape
+- [ ] Pre-tax income calculation; `EffectiveTaxRate` field on Budget entity + migration
+- [ ] React Summary page: income header cards, type breakdown table, pre-tax section
+- [ ] Editable tax rate on Summary page (PATCH to budget settings)
+- [ ] Verify clean build
+
+### Phase 7 — Budget Settings & Sharing UI
+- [ ] Budget list / selector page (landing page after login)
+- [ ] Budget Settings page: rename, tax rate, shares table
+- [ ] Share add flow: input email address, choose permission, submit; show "pending" badge for users not yet seen
+- [ ] `BudgetNav` tab component used across all budget pages
+- [ ] Verify clean build
+
+### Phase 8 — Polish & Production Readiness
+- [ ] Global error boundary and API error toasts in React
+- [ ] Loading skeletons for tables
+- [ ] Confirm-on-delete dialogs
+- [ ] EF Core migration applied automatically on startup (`context.Database.MigrateAsync()`)
+- [ ] Health check endpoint (`/healthz`)
+- [ ] Final Dockerfile review and end-to-end smoke test inside Docker
+- [ ] Verify clean build
+
+---
+
+## Open Questions / Deferred Decisions
+
+- **Optimistic vs. server-side updates**: The React tables can either update locally then sync, or round-trip to the server. Phase 4–5 will use server-round-trip for simplicity; can add optimistic updates in Phase 8 if the UX feels slow.
+- **Row reordering persistence**: Drag-to-reorder uses a `SortOrder` integer column. The reorder endpoint accepts an ordered list of IDs and bulk-updates SortOrder. This is straightforward but may need debouncing if the user drags frequently.
+- **Auth client registration**: Before Phase 2 can be fully tested end-to-end, a client must be registered in the Auth admin UI for the Budget app. Required fields: client type = Public, grant = Authorization Code + PKCE, redirect URI = `http://localhost:5173/callback` (dev) + production URL, scopes = `email profile roles`.

+# React + TypeScript + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
+
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+
+```js
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+
+      // Remove tseslint.configs.recommended and replace with this
+      tseslint.configs.recommendedTypeChecked,
+      // Alternatively, use this for stricter rules
+      tseslint.configs.strictTypeChecked,
+      // Optionally, add this for stylistic rules
+      tseslint.configs.stylisticTypeChecked,
+
+      // Other configs...
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
+
+You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+
+```js
+// eslint.config.js
+import reactX from 'eslint-plugin-react-x'
+import reactDom from 'eslint-plugin-react-dom'
+
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+      // Enable lint rules for React
+      reactX.configs['recommended-typescript'],
+      // Enable lint rules for React DOM
+      reactDom.configs.recommended,
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
